Are there cabins for 2 available in train K1512/K1513 Nanjing-Yichang, private bathroom? Soft sleeper

Hi, the train K1512/K1513 starts from Wuxi and has a stop at Nanjing. Since the distance between Nanjing and Yichang is not very long, there should be few deluxe soft sleepers available. Thus, you would better purchase the common soft sleeper tickets at the train station directly.
